I hope you can help me with this, it's driving me insane.
I noticed the problem first when shooting into a blue sky with clouds at a wedding, then I saw the problem on a table the next shoot as well. Now I checked with a white wall and found that Lightroom actually does this to my newly picked up Tamron 17-70 2.8 (on a Fuji XT-4)
I'm having crazy rings and vignetting with the Tamron lens, first thought it's the lens, but it's Lightroom adding the crazy rings. Since when I'm importing there's nothing, but when i hover over the image and select it, it takes a second and then Lightroom adds them to the picture, as if it where implementing a lens correction, but horribly wrong. Turning off Lens Profile / Correction doesn't do anything, once it's there it's there. Also the JPEG looks fine, it's only the raw file.
Attached are the two images, it's easy to tell which one is the JPEG sooc and which is the RAW file out of Lightroom with the "vignette"
Can you please tell me how to fix this, and what is going on there?
